You are not giving an explanation of what you actually want. Please stop for a second and describe in detail what you want.

Do you want a program that computes the indefinite integral or antiderivative or do you want a program that just outputs an approximation of the area under the curve of a function from one point to another.

If it is the former, then there is many many pages of research on the subject and I would direct you to wolfram alpha as it has a decent integral calculator. However, there is no way to compute all integrals.

Consider the function e^{x^2}. Integrate it. No, you don't know how? Yeah, that is because it is the most infamous example of a function whose integral cannot be written in terms of any functions you have studied up till now. The solution was for people to literally slap a name on it (and call its indefinite integral the error function).

So, you cannot program a general purpose integral calculator. It isn't possible.
